While not as popular as betting against the point spread in sports gambling, betting the “over/under” isn’t that far behind. Sometimes you may see this as O/U, over-under, over under or simply referred to as “the over” or “the under.”

Las Vegas Sports Betting 101: How to Bet on Sports in Las Vegas Every year, thousands of sports enthusiasts flock to Las Vegas to place their bets and closely watch their teams with dollar signs in their eyes. The first step is learning how sports betting works and understanding some of the language and terminology that bettors use. Over the coming days and weeks, we will be using this space to discuss several Sports Betting 101 topics.

What does over under mean in betting?

Simply stated, it is the total of the points scored by both teams. While all sports employ an over/under betting option, by far the most money wagered on this bet is in football and basketball. Sports like baseball and hockey offer over/under options, but the vast majority of bets on those sports in based on the established “money line” to pick a winner at a set price.

Unlike a point spread bet in which you are aligning yourself with one team, you’re betting on both teams – either their offenses or the defenses – when betting the over/under. Sports books set over/under scores on games based upon numerous factors.

In the NFL, most over/under scores are set in the low-to-mid 40s.In college football, over/under scores are usually in the high-40 to low 50s – in the Big 12, the land that defense forgot, it can hit the 60s.In the NBA, a typical over/under tends to hover in the 210 range. In college basketball, a standard over/under is between 140 and 155.

The hidden factors that come into play in determining a point spread vary by sport, but have common themes. Recent team history is a primary factor that sports books like to exploit. Sports by their nature are a reflective business based on developing trends from previous games (“getting on a roll”) and, if a football team has scored 40-plus points in three straight games, the over/under is going to be higher because sports bettors tend to believe that trends are going to continue. It’s human nature…until they don’t.

If a critical player – a quarterback in football or a dominant scorer in basketball – is out or playing injured, the over/under will drop.

Other factors critical in setting the over/under number include weather (where applicable), an undefinable history between teams (you know Steelers-Ravens games are going to be physical bloodbaths) and injuries that may not jump out to casual fans that mean a lot sports books are all factors that go into creating and setting an over/under line that will draw an even number of fans to both sides of the number.

The key to betting the over/under is to look at a slate of games without knowing what the over/under is and set what you believe it should be based on your knowledge of those two teams. The ones that differ the most from what you think should be are the ones to place your bets on.

One final note that has been a mantra of those who bet the over/under with some consistency – every game is under until it goes over.

If you’re new to sports betting, start with picking and choosing games you’re convinced should go under and get an understanding of how late-game fireworks can botch your plans.

Here’s a simple example:

LA Lakers -4.5

NY Knicks +4.5

The Lakers are 4.5 point favorites in this game which means they have to win by 5 points or more for you to win your bet. If they win the game by 1-4 points (or lose) then you lose your bet.

Knicks bettors have two ways to win. They can win the game outright or lose by 4 points.

Here’s a simple example:

Patriots at Packers Under/Over 44.5

You bet on the Over if you’re expecting 45 points or more.

You bet on the Under if you’re expecting 44 points or less.

Sportsbooks love parlay bettors as they tend to lose at a much faster rate than individual bets.

1. An amount that corresponds to 1% of a bettor’s bank; or

2. An amount equal to one regular wager for that bettor

Some bettors outlay the same amount per game – this is flat betting. Others bet a varying percentage of their bankroll per game depending on the odds available and their confidence level of that play. That is almost always between 1-5% of your total bankroll.
